capturing the results of d.where -- a intermitant problem!

Hello GRASS People,
I am working with a shell script which puts up an image and invites the user to
select a site. The d.where command is used and the output is placed in a file.
The problem is that I get an error on the stdin ( the mouse button generated
long lat data ), but only sometimes. This occurs under both of the following
methods of capture:
1) d.where > file
2) cat > file <<eof
` d.where `
Is there some option to control how sensitive ( robust ) the stdin I/O is for
the mouse? d.where doesn't seem to have any pertinent options. What is the
safest way to trap input from d.where?
As always, you help is very much appreciated!
